PROBLEM TO BE SOLVED: To provide cured phenol resin particles having small average particle size. SOLUTION: In the presence of an alkylbenzenesulfonic acid, a protective colloid and a surfactant, phenols and aldehydes are allowed to react to produce uncured phenol resin particles. Then, the uncured phenol resin particles are hardened to obtain the target cured phenol resin particles. COPYRIGHT: (C)2006,JPO&NCIPI
